Answer:
Step-by-step explanation:
Find the width as below
- l² + w² + h² = d², where l- length, w- width, h- height, d- the distance between top and bottom corners
Substitute the values and solve for w
- 4² + w² + 12² = 13²
- w² + 160 = 169
- w² = 9
- w = 3 feet
Now find the volume
- V = lwh
- V = 4*3*12 = 144 ft³

Step-by-step explanation: An equilateral triangle means all 3 sides are the same length.
A square also have the same length for all 4 sides.
So each side of the square is 6cm, to find the perimeter you do 6*4=24.
then divide the square's perimeter by 3 since triangle have 3 sides. 24/3=8
so each side of the triangle will be 8cm
